IMPROVEMENT IN PORTABLE RANGES.

Specification forming part of Letters Patent No. 153,900, dated August1l, 1874; aPPHGMOD filed September 3, 1873.

To all whom Ait may concern:

Be it known that I, FEEDEIGK J. KENNY, of Boston, Massachusetts, haveinvented Im provements in Portable Ranges, of which the following is aspecification:

This invention relates to the class of stoves known to the trade asportable ranges.

Like letters indicate like parts in all the drawings.

Figure I is a perspective view of the range. Figs. II, III, and IV aresectional views of the same.

A is the re-pot, surrounded by coil-pipe a; b, the grate forming thebottom of the lire-pot. c is the sifting-grate. B B are the coal-boxes.G is the ash pit or box; D D, the water-heaters, d, the lines under thepot-holes; c, the blower 5 f, the damper in front of upper part offire-box 5 g, the hinges of the water-heaters5 h, the side dampers 7c,the back damper; l, damper which controls the flow of the products ofcombustion in the exit-passage, E, the uptake; F, the enlargement of theuptake; G Gr, the ovens 5 H, the hot-closet; I, the draft-regulator; m,the draft-damper; n, slide closing the opening in the regulator I; K,the waterback. p is the ledge around the outside of the ovens to receivethe lagging. q is the partial partition of the draft-regulator. r and rare the parts of the funnel leading to the chimney-on each side'of theregulator.

The stove or range may be considered in two parts-the base or lowerdivision, containing the fire-pot A, ash and coal boxes B and G,hot-water tanks K and D, and ilnes under the pot-holes d; and the upperpart or division, which includes the ovens G, hot-closet H, andregulator I. The base or lower part of the range is built with thefire-pot A in the center of the front half, a coiled water-pipe, a,connected with water-back K, surrounding and forming the sides. Thebottom is a sliding removable grate, b, resting on ledges on the side ofthe firepot. Underneath this grate is a hip-grate, c, with its centerhigher than the ends, the grate-bars sloping from the center to thecoal-boxes B B arranged on either side. The ashes from the re fall onthe inclined grate-surfaces c, and the line ashes sift into the ash-pitO, and the coal slides down on either side into the coal-boxes B Bplaced to receive it, and which, as well as the ashreceiver G, arearranged as drawers. The iront of the stove is made as a blower, e,closing the lower part of the fire-pot. Above this is a door suspendedby hinges, and which opens outward and downward, and forms a top damper,f. Adjoining the tire-pot on each side, and forming the two frontcorners of the stove below the pot-tlues d, are two reservoirs, D, forhot water, which are hung upon hinges g at the sides of the stove, andcan be swung upon said hinges outwardly, so that their contents can bereached from the front or ends of `the range, as may be desired. On eachside and at the back of the fire-pot are dampers hand k, placed toregulate the passage of the heat to the side or pot ilues d and to theuptake E. The back damper 7c is generally closed when boiling is goingon, and the side dampers h when a hot quick oven is desired. Each ofthese dampers has a coal-guard, s, on the lire-pot side. The entire backof the lower division, below the pot-lines d, is a hot-water tank orreservoir, K, the water being heated by passing through the coil-pipes athat surround the nre-pot, and by direct contact of the re with theplate of the water-back. rllhis reservoir K is of sufficient size toanswer all the purposes of the ordinary boiler or hot-water tank usedwith ranges. The uptake E runs to the fines surrounding the two circularor oval ovens Gr, which are made of single sheets of sheet-iron, andremovable from the surrounding frame, if desirable. Above the uptake thetlue is divided into two parts, each passing completely around thecylindrical ovens G as a single-sheet iue, and uniting again just abovethe point of separation. The ovens are formed with a ledge at the edgesp, which may be lagged to prevent radiation. In the uptake E is adamper, l, by which the heat can be completely turned oft' from oneoven, if desired. The ovens G are made cylindrical or oval, andsurrounded by singlesheet lues, leading rst outward and upward, thenupward and inward, then inward and downward. From the upper end of theuptake E the smoke-passage enlarges into two chambers, F, one on eachside. These cominunicate with the smoke passages or fines around theovens G. Through a door, L, in

bined With the tire-pot A and ilue'sl d, in the manner and for thepurposes set forth.l

3. The uptake E, chambers F, damper l, and ovens G, having the singlesheet iiue, the several parts combined in the manner and for thepurposes set forth.

4. The combination of the fire-pot A, coilpipe a, water-tank K, iiues d,with the hinged reservoirs D, substantially as and for the purposes setforth.
